Patent GB-190421106-A (GB)
Title: Automatic Feed Regulator for Boilers, Heaters, and the like.
Inventor: BICE WALTER HENRY
Filed: 1904-10-01
Granted: 1905-06-08
Abstract: 21,106. Bice, W. H., and Bice, A. W. Oct. 1. Liquid levels, regulating.-A rod, rotated by the rise and fall of a float in a boiler, reservoir, &c., causes the rotation of a disc having radial openings between two other discs with similar apertures. These, together with screw valves, regulate the supply of steam to a feedwater pump, and in the case of tanks &c. the amount of discharge into them from a pump is controlled in a similar way. The inclined rod 32, attached to the float 31, can rotate the rod 24, which passes through the coupling 22 into the valve-box 23, a sectional plan of which is given in Fig. 5. The shaft 24 is tapered at b and fits into the central hole 36 in the disc 34, pierced with radial openings d<2>, e<2>, f<2>, g<2>, Figs. 6 and 7, being retained by the nut 29. On either side of the disc are two similar discs 37, 40, pierced in a similar manner except that the holes corresponding to g<2> are narrower. The disc 37 is peripherally screwed and the disc 40 is retained in position by a screw 42 and the flanged screwed ring 44. The valve casing is pierced with three passages corresponding with the slits in the discs, and each may be closed by means of the screw valves 55. Another passage 49 in line with the opening g<2> may be connected with a bye-pass at 50. A spring-controlled valve 57 is for use in connection with a boiler. When used for pumping oil &c. into tanks, the pipe 48 is in communication with the suction side of a pump, and the pipe attached at 50 with the discharge side. In this case, the holes in the discs are in line when the liquid is at the correct level, so that it passes from the one side of the pump to the other through the passage 49. When the level falls, the liquid can no longer pass through the discs, and is therefore discharged into the tank or other receptacle. To prevent undue motion of the float, it may be surrounded by a cage.

Title: Improvements in Screws and Bolts.
Inventor: THOMSON JOHN
Filed: 1904-10-04
Granted: 1904-11-10
Abstract: 21,290. Thomson, J. Oct. 4. Bolting, methods of.-Relates to a screwed bolt which, when subjected to sufficient pressure, automatically withdraws itself from engagement with its nut or similar member without destroying the threads. The screwed bolt 9, Fig. 1, is shown securing the end of a cylinder 7 of a steam engine, pump, water meter, or the like. The threads have a V-shaped section and are preferably flattened or rounded at the root and apex. One end of the bolt is longitudinally slotted at 12, 13, Fig. 4, to form a number of prongs 14. These prongs, when screwed into a nut or other member, collapse and spring inwardly when their resistance to the inward thrust due to the angle of the thread is overcome, as in Fig. 5, and to such an extent that the nut and bolt are disengaged. To facilitate the automatic springing back of the prungs 14 when free of the nut, a groove 15 is formed under the head. The prongs may be made to yield to different loads by varying the width and number of the slots, the angle of the thrust-resisting face of the thread, or the lengths of the prongs, or by boring a hole 16, Figs. 4 and 5, through the centre of the bolt. The bolt may be internally screw-threaded, the prongs being adapted to be expanded outwardly to disengage with an externally-threaded nut.

Title: Improvements in connection with Cylinders and Valves for Locomotive and other Engines.
Inventor: SISTERSON GEORGE ROBERT
Filed: 1904-12-29
Granted: 1905-12-29
Abstract: 28,761. Sisterson, G. R., and Mitchell, G. Dec. 29. Compound engines; cycles.-The invention is particularly applicable to engines, such as locomotives having two cylinders of the same size. After a part of the stroke of the first piston has been performed, communication is opened with the corresponding end of the second cylinder and almost simultaneously with the opposite end of the first cylinder, the exhaust port of which has been closed to the atmosphere somewhat earlier. Boiler steam may also be admitted to the second cylinder under heavy loads. In three and four cylinder engines, particularly in engines where the cylinders are of different sizes, the first cylinder valve may have so much inside lap that no exhaust escapes to the atmosphere but all enters the second cylinder. Slide valves.-Several forms of valves to carry out the above system of working are described. Fig. 1 shows two flat valves for the inside cylinders of a locomotive. The valve c admits steam to one end of the first cylinder a while exhaust steam from the other end escapes to the atmosphere through the passage g ; the two ends of the cylinders are then put into communication with the cylinder b by means of the passages h, h<1> and the valve d. The cylinder b exhausts through the passage l. Ports o, o<1>, shown in dotted lines, admit high-pressure steam to the cylinder b. Fig. 5 shows a piston valve for the first cylinder ; the extreme ends of the valve-chest contain highpressure steam and the passage u leads to the second cylinder valve-chest. Two other flat slide valves for the high-pressure outside cylinders of a locomotive are described, having a slightly different arrangement of ports. The two valve-chests may have a three-way cock between them, by which they are cut off from one another and steam is admitted to the second chest.

Title: Improvements in and relating to Aerating and Bottling Apparatus.
Inventor: LEE WILLIAM
Filed: 1905-02-10
Granted: 1906-02-10
Abstract: 2788. Higginson, G. Feb. 10. Bottling.-In an aerating and bottling machine, a water chamber h and syrup chamber e are adapted to be placed in communication with gas, water, and syrup inlet pipes, and with an outlet pipe d and a duct p leading to a rotary bottle frame by ducts in a rotatable or sliding disk f. The gas pressure actuates a pneumatic pad on the bottle frame and also a guard. In operation, the disk is turned to connect the chamber h with the water inlet a and with an outlet pipe d, and the syrup chamber e with a syrup pipe c. The chamber h becomes filled with water, which escapes down a duct k to the outlet tube, and syrup is forced into the chamber e either under a head or by gas pressure. The disk f is then turned into the position shown in Fig. 1, opening communication by a duct n between the gas-supply tube b and the chamber h, by a duct o between the chambers h, e, and by a duct p between tne chamber e and the bottling-apparatus. Gas entering the chamber h forces the water into the chamber e, where it mixes with syrup and thence passes into the bottle q. The bottle frame is given a half-turn, when the pressure in the bottle is snifted through a port t. The frame is returned, when more liquid and finally gas enter the bottle. The disk f is turned and snifts off the pressure in the chamber h and in the bottle neck, the stopper x being forced into the neck of the bottle. The movement of the disk which opens the gas port b also establishes connexion through ducts 3 between the gas supply and a pneumatic pad 2, to hold the base of the bottle, The gas pressure also operates a bottle guard 6 by an india-rubber or like casing 12 in the pad 2 forcing outwards a plunger 7 against the action of a spring 8. The bottle guard consists of two semicircular parts 24, 25, one 24 fixed to the casing, and the other 25 adapted to be rotated by an arm 28, which projects into a camgroove 10 in the plunger. The syrup chamber e may be dispensed with.

Title: A New and Improved Method of and Apparatus for Detecting Electrical Oscillations.
Inventor: WALTER LOUIS HEATHCOTE
Filed: 1906-02-24
Granted: 1906-11-22
Abstract: 4535. Walter, L. H. Feb. 24. No Patent granted (Sealing fee not paid). Telegraphs.-A magnetic detector for wireless telegraphy produces a unidirectional current by opposing two equal, dynamically-produced, electromotive forces, and causing the oscillations to act upon one of two magnetic bodies undergoing reversals of magnetism in the respective generator fields, whereby one generator develops a greater electromotive force than the other. Two equal circuits C', C<3> at right-angles to each other are placed between magnet poles D<1>, D' and connected to a commutator F having brushes E<1>, E<2> in circuit with a relay or recording instrument G, which will show no deflexion, as the electromotive forces produced neutralize each other. Mounted on the same shaft are two bobbins B<1>, B<2> of insulated iron wire. The oscillations are passed through the bobbin B' by way of brushes H<1>, H' and slip rings I', I<2>, thus causing the electromotive force in one of the circuits C', C<3> to overpower the other and so producing a unidirectional current. A telephone J may be used to receive the signals simultaneously by connecting it through slip rings K<1>, K<2> to the circuits C', C<3>. In a modified form, the bobbins of iron wire are secured to an independent but concentric shaft so that the circuits C<1>, C<3> can be rotated quicker than the bobbins, which is stated to give a better effect. In the modification shown in Fig. 3, the magnet system D', D<2> rotates instead of the circuits C', C<3>,and the bobbins are arranged to be rotated in opposite directions, the commutators being fixed and the brushes rotating with the magnet system. The oscillations in this case are made to affect both bobbins of iron wire, thus doubling the effect. In the last modification, shown in Fig. 4, the magnetic masses on the bobbins B', B<2> are placed one on each side of an ordinary Gramme-ring armature N<1>, N' in the same magnetic field. The effect of the oscillations on the bobbin B' in this case is to reduce the reluctance of the magnetic circuit of the system D<1> during the time such oscillations are acting. This construction is more suitable when the available energy is large.
